The world’s best fusion reactor, situated in the heart of the merry, Hobbit-inspiring motherland of Oxfordshire in England, will soon attempt to become the first fusion power experiment to surpass the mythical “break-even” point. This experiment, known as the Joint European Torus (JET), has held the world record for fusion reactor efficiency since 1997 despite the USA’s recent laser-based fusion experiments at the National Ignition Facility. If JET can reach break-even point, there’s a very good chance that the massive ITER reactor currently being built in France will be able to obtain the holy grail of everlasting green power generation: self-sustaining fusion.
